“Dr. Iron Fists” Vitali Klitschko!
Vitali Volodymyrovych Klitschko (/vɪˌtæli ˈklɪtʃkoʊ/; Ukrainian: Віта́лій Володи́мирович Кличко́ [wiˈtɑl⁽ʲ⁾ij woloˈdɪmɪrowɪtʃ klɪtʃˈkɔ]; born 19 July 1971) is a Ukrainian politician and former professional boxer. He currently serves as Mayor of Kyiv and head of the Kyiv City State Administration, having held both offices since June 2014.
Klitschko is a former leader of the Petro Poroshenko Bloc and a former Member of the Ukrainian Parliament. He became actively involved in Ukrainian politics in 2005 and combined this with his professional boxing career until his retirement from the sport in 2013.
As a boxer, Klitschko is a three-time world heavyweight champion, the second-longest-reigning WBC heavyweight champion of all time and has the fifth-longest combined world championship reign in history at 2,735 days. He held the WBO title from 1999 to 2000; the Ring magazine title from 2004 to 2005; and the WBC title twice in 2004 and between 2008 and 2013.
Standing at 2.01 metres (6 feet 7 inches) and usually coming into fights around 250 pounds, Klitschko was renowned for having exceptional ring dominance. With an 87% knockout percentage, he holds the third highest knockout-to-fight ratios of any world champion in heavyweight boxing history, behind Deontay Wilder and Rocky Marciano while also possessing a highly durable chin.
Vitali Klitschko defeated two world champions (Herbie Hide and Samuel Peter) and five former world champions (Orlin Norris, Corrie Sanders, Juan Carlos Gómez, Shannon Briggs and Tomasz Adamek) in the course of his career; several other boxers he beat were ranked within the global top ten by BoxRec within a year of him beating them (including Danny Williams, Chris Arreola, Odlanier Solis, and Derek Chisora).
Klitschko was still the reigning WBC world heavyweight champion at 42 years of age when he finally announced his retirement in December 2013. His only two losses came via a shoulder injury and a deep cut above his eye, both of which were recorded as stoppages rather than outright knockouts; in both fights he was leading on the judges’ scorecards.
Klitschko is one of nine boxers to defeat at least ten different fighters for the world heavyweight title. Vitali has defeated 15 boxers for the world heavyweight title, the fifth-most in history (tied with Lennox Lewis). He is the only heavyweight boxer to have reigned as world champion in three different decades. Along with Oliver McCall and Nikolai Valuev, he is also the only world heavyweight champion to have never been knocked down in any fight.
Klitschko and George Foreman are the only heavyweight boxers in history to defend a world title after turning 40. Being the first professional boxing world champion to hold a PhD degree, and in reference to his punching power, Klitschko’s nickname was “Dr. Ironfist”. His younger brother, Wladimir, is a former unified world heavyweight champion. From 2006 until 2015, Vitali and Wladimir dominated heavyweight boxing, a period typically known as the “Klitschko Era” of the division.
